Abstract

Recent studies have generated conflicting data regarding the bioaccumulation and toxicity of leachates from preservative-treated wood. Due to the scale of the wood preserving industry, timber treated with the most common preservative, chromated copper arsenate (CCA), may form a significant source of metals in the aquatic environment. The existing literature on leaching of CCA is reviewed, and the numerous factors affecting leaching rates, including pH, salinity, treatment and leaching test protocols are discussed. It is concluded from the literature that insufficient data exists regarding these effects to allow accurate quantification of leaching rates, and also highlights the need for standardised leaching protocols.

摘要

近期研究就防腐处理木材渗滤液的生物累积和毒性得出了相互矛盾的数据。由于木材防腐行业的规模，用最常见的防腐剂铬酸铜砷酸盐（CCA）处理过的木材可能会成为水生环境中金属的一个重要来源。本文回顾了关于CCA浸出的现有文献，并讨论了影响浸出率的众多因素，包括pH值、盐度、处理方式和浸出试验方案。从文献中得出的结论是，关于这些影响的数据不足，无法准确量化浸出率，同时也强调了标准化浸出方案的必要性。
